TECHNICAL FIELD

The present disclosure relates to the technical field of electronic cigarettes, in particular to an atomizer and an electronic cigarette having the same.

BACKGROUND

Electronic cigarettes have a shape and mouthfeel similar to cigarettes, and are mainly used to quit smoking and replace cigarettes. An electronic cigarette generally includes an atomizer and a battery assembly. The atomizer includes a mouthpiece, a liquid reservoir, and an atomizing core. The liquid reservoir is used to store liquid, the atomizing core is used to atomize the liquid in the liquid reservoir, and the atomized liquid is inhaled by the user after discharging from the mouthpiece. The battery assembly is electrically connected to the atomizing core and is used to provide power to the atomizing core, so as to atomize the liquid.

During the process of atomizing liquid, a carbon deposit will be produced and adhere to the atomizing core. After the electronic cigarette is used for a period of time, the atomizing core may require to be replaced, otherwise the carbon deposit on the atomizing core will affect the taste of smoking. In a conventional atomizer structure, the housing of the atomizing core is directly inserted into the liquid reservoir, and the liquid storage cavity of the liquid reservoir directly contacts the atomizing core. When replacing the atomizing core, the atomizing core is pulled out directly from the liquid reservoir. When the atomizing core is pulled out, the residual liquid in the liquid storage cavity will also flow out, which may contaminate hands, cause the waste of liquid, and increase the user's cost.

Referring to FIG. 1 to FIG. 2, an atomizer according to an embodiment is provided, which includes a liquid reservoir 10, an atomizing core 20, and a mouthpiece 30. The liquid reservoir 10 is provided with a liquid storage cavity 110 and an accommodating channel 120 in communication with the liquid storage cavity 110. The atomizing core 20 is movably disposed in the accommodating channel 120, and the atomizing core 20 is in communication with the liquid storage cavity 110. The mouthpiece 30 is movably disposed in the accommodating channel 120, the mouthpiece 30 movably abuts against the atomizing core 20, and the mouthpiece 30 is configured to push the atomizing core 20 out of the accommodating channel 120 and movably block the liquid storage cavity 110.

In the aforementioned atomizer, the liquid reservoir 10 is provided with the liquid storage cavity 110 and the accommodating channel 120, and the accommodating channel 120 is in communication with the liquid storage cavity 110. The atomizing core 20 and the mouthpiece 30 are respectively movably disposed in the accommodating channel 120, and the atomizing core 20 is in communication with the liquid storage cavity 110, such that liquid in the liquid storage cavity 110 can enter the atomizing core 20 to be atomized. By pushing the mouthpiece 30 into the accommodating channel 120, the mouthpiece 30 pushes the atomizing core 20 out of the accommodating channel 120. Meanwhile, the sidewall of the mouthpiece 30 blocks the liquid storage cavity 110 to prevent liquid in the liquid storage cavity 110 from entering the accommodating channel 120. The atomizer of the present disclosure has a simple structure, is convenient to operate, and can prevent liquid leakage when replacing the atomizing core 20, thus saving liquid and preventing liquid from contaminating hands.

Referring to FIG. 3 and FIG. 5, specifically, the liquid reservoir 10 is provided with a partition wall 130 therein. The partition wall 130 separates the liquid reservoir 10 into the accommodating channel 120 in a middle portion and the liquid storage cavity 110 surrounding the accommodating channel 120. The liquid storage cavity 110 is used to store liquid. The partition wall 130 is provided with a liquid outlet 131, and the accommodating channel 120 is in communication with the liquid storage cavity 110 through the liquid outlet 131.

The atomizing core 20 is movably disposed in the accommodating channel 120, and the atomizing core 20 is in communication with the liquid outlet 131. The mouthpiece 30 is movably disposed in the accommodating channel 120, the mouthpiece 30 movably abuts against the atomizing core 20, and the mouthpiece 30 is used to push the atomizing core 20 out of the accommodating channel 120 and movably block the liquid outlet 131.

In the aforementioned atomizer, by pushing the mouthpiece 30 toward the accommodating channel 120, the mouthpiece 30 will abut against the atomizing core 20, and the atomizing core 20 can be pushed out of the accommodating channel 120. When pushing the mouthpiece 30, the sidewall of the mouthpiece 30 is moved to block the liquid outlet 131, such that liquid in the liquid storage cavity 110 is prevented from leaking from the liquid outlet 131, which avoids contaminating hands, keeps the hands clean and saves the cost of liquid.

In order to increase the volume of the liquid storage cavity 110 and to increase the storage capacity of liquid, as shown in FIG. 3, in one of the embodiments, the partition wall 130 is enclosed to form the accommodating channel 120, and the liquid storage cavity 110 disposed surrounding of the accommodating 120. Since the liquid storage cavity 110 and the accommodating channel 120 are separated by the partition wall 130, and the liquid storage cavity 110 is arranged around the accommodating channel 120, the volume of the liquid storage cavity 110 is increased. In the illustrated embodiment, the partition wall 130 is not only a cavity wall of the liquid storage cavity 110, but also a sidewall of the accommodating channel 120. By increasing the volume of the liquid storage cavity 110 and the storage capacity of liquid, the number of liquid injections by the user can be reduced, the use time after a single liquid injection can be prolonged, the frequency of liquid injection can be reduced, and the use convenience of atomizer can be improved. Meanwhile, by arranging the liquid storage cavity 110 around the accommodating channel 120, the heat transfer rate during the heating of the atomizing core 20 is reduced, thus avoiding the discomfort of the user caused by the high temperature of the outer peripheral surface of the liquid reservoir 10. In one of the embodiments, the liquid outlet 131 is in communication with the accommodating channel 120, and then the accommodating channel 120 is in communication with the liquid storage cavity 110 via the liquid outlet 131. The liquid in the liquid storage cavity 110 can flow into the accommodating channel 120 from the liquid outlet 131, and then enter the atomizing core 20. In order to improve the liquid flowing speed. In one of the embodiments, the partition wall 130 is provided with two or more liquid outlets 131. By increasing the number of liquid outlets 131, the liquid can flow into the atomizing core 20 through the plurality of liquid outlets 131 to increase the smoke concentration during atomization. In one of the embodiments, in order to make liquid in uniform contact with the atomizing core 20, two or more liquid outlets 131 are evenly spaced, such that liquid uniformly enters the atomizing core 20 from multiple directions, so as to avoid a local carbon deposit in the atomizing core 20 caused by excessive liquid at local portions.

In order to concentrate the smoke from atomized liquid heated by the atomized core 20 and make the smoke enter the mouthpiece 30, so as to avoid the smoke from escaping, as shown in FIG. 4, in one of the embodiments, the mouthpiece 30 is provided with a smoke channel 310. One end of the atomizing core 20 extends at least partially into the smoke channel 310. One end of the smoke channel 310 is in communication with one end of the atomizing core 20, and another end of the smoke channel 310 is use to discharge smoke for the user to inhale. By partially extending one end of the atomizing core 20 into the smoke channel 310, the smoke can be accurately introduced into the mouthpiece 30 and inhaled by the user. In one of the embodiments, the mouthpiece 30 may be a general mouthpiece on the market.

In order to prevent liquid from leaking into the user's mouth from a gap between one end of the atomizing core 20 and the sidewall of the smoke channel 310, as shown in FIG. 3 and FIG. 4, in one of the embodiments, a first seal ring 210 is sleeved on the end of the atomizing core 20. The first seal ring 210 is located in the smoke channel 310 and in interference fit with the smoke channel 310, therefore, it can block the gap between the atomizing core 20 and the smoke channel 310 and prevent liquid from entering the smoke channel 310 through the gap.

In order to position the first seal ring 210, as shown in FIG. 3 and FIG. 4, in one of the embodiments, the atomizing core 20 is provided with a first positioning groove 220 on a sidewall of one end thereof, and the first seal ring 210 is fit in the first positioning groove 220, thereby preventing the first seal ring 210 from moving. In order to enhance the sealing effect, in one of the embodiments, the number of the first seal rings 210 is two or more. Accordingly, the number of the first positioning grooves 220 is also two or more, and the two or more first positioning grooves 220 are arranged at intervals. Each first seal ring 210 is placed in a corresponding first positioning groove 220. In one of the embodiments, the first seal ring 210 is made of elastic soft materials, such as rubber, silicone, or polyurethane, which is not limited hereto. By using the elastic soft material, the first seal ring 210 is elastic and convenient for disassembly and assembly, while maintaining an interference fit with the smoke channel 310.

In order to prevent the atomizing core 20 from completely entering the smoke channel 310 of the mouthpiece 30, as shown in FIG. 3, in one of the embodiments, the atomizing core 20 is provided with a step portion 230 on a sidewall thereof, and the step portion 230 abuts against the mouthpiece 30. In one of the embodiments, the step portion 230 abuts against one end of the mouthpiece 30 adjacent to the atomizing core 20. The outer diameter of the step portion 230 is larger than the inner diameter of the smoke channel 310, so as to prevent the atomizing core 20 from excessively entering the smoke channel 310. It is only necessary that the atomizing smoke outlet end of the atomizing core 20 enters the smoke channel 310, such that the smoke is buffered in the mouthpiece 30 before entering the mouth of the user, thus it is avoided that too short smoke distance will affect the user's smoking taste. As shown in FIG. 7, one end of the mouthpiece 30 abuts against the step portion 230. When the mouthpiece 30 is pushed from one end of the accommodating channel 120 into the accommodating channel 120, the mouthpiece 30 pushes the atomizing core 20 by abutting against the step portion 230, such that the atomizing core 20 is pushed out from the other end of the accommodating channel 120. In this embodiment, one end of the accommodating channel 120 is an end adjacent to the user, and the end of the accommodating channel 120 is an end away from the user. In one of the embodiments, the outer diameter of the mouthpiece 30 corresponds to the inner diameter of the accommodating channel 120. After the mouthpiece 30 is placed in the accommodating channel 120, the outer sidewall of the mouthpiece 30 is in contact with the sidewall of the accommodating channel 120, such that the mouthpiece 30 is fixed in the accommodating channel and prevented from falling off. By pushing the mouthpiece 30 into the accommodating channel 120, the mouthpiece 30 moves in the accommodating channel 120, and the outer sidewall of the mouthpiece 30 gradually blocks the liquid outlet 131 until the outer sidewall of the mouthpiece 30 completely blocks the liquid outlet 131, so as to prevent liquid from leaking from the liquid outlet 131.

In order to facilitate pushing the mouthpiece 30 and the atomizing core 20, as shown in FIG. 4, in one of the embodiments, the total length of the mouthpiece 30 and the atomizing core 20 after abutting against each other is greater than the length of the accommodating channel 120. In one of the embodiments, the length of the mouthpiece 30 is less than the length of the accommodating channel 120, the length of the atomizing core 20 is also less than the length of the accommodating channel 120, and the total length of the mouthpiece 30 and the atomizing core 20 is greater than the length of the accommodating channel 120, thus preventing both of the mouthpiece 30 and the atomizing core 20 from being located inside the accommodating channel 120 and is inconveniently to exert force. Since the total length of the abutting mouthpiece 30 and atomizing core 20 is greater than the length of the accommodating channel 120, at least a part of the mouthpiece 30 or a part of the atomizing core 30 is exposed outside the accommodating channel 120. When a part of the mouthpiece 30 is exposed outside one end of the accommodating channel 120, the atomizing core 20 can be pushed out from another end of the accommodating channel 120 by pushing the mouthpiece 30. After the atomizing core 20 is replaced, the replaced atomizing core 20 abuts against one end of the mouthpiece 30, and a force is exerted to the atomizing core 20 in the opposite direction from another end of the accommodating channel 120. While the replaced atomizing core 20 is pushed into the accommodating channel 120, the mouthpiece 30 is pushed out by the atomizing core 20 from one end of the accommodating channel 120 in the opposite direction, and a part of the mouthpiece 30 is exposed outside the accommodating channel 120 again for the user's mouth to suck through the mouthpiece 30.

When the user purchases a plurality atomizing cores 20 with different sizes for backup, some atomizing cores 20 in smaller size may not be fixed in the accommodating channel 120. In order to fix the atomizing core with a smaller outer diameter, as shown in FIG. 4 and FIG. 6, in one of the embodiments, the atomizer further includes a sleeve 40, which is detachably disposed in the accommodating channel 120 and is sleeved on the atomizing core 20. The sleeve 40 is in communication with the liquid outlet 131, such that after liquid flows out of the liquid outlet 131, liquid can flow through the sleeve 40 and then enters the atomizing core 20. When the outer diameter of the atomizing core 20 is less than the inner diameter of the accommodating channel 120, the sleeve 40 sleeved at the outside of the atomizing core 20 can fill the gap between the atomizing core 20 and the accommodating channel 120, such that the atomizing core is fixed in the accommodating channel 120. As shown in FIG. 4, in one of the embodiments, the outer diameter of the sleeve 40 is no less than the inner diameter of the accommodating channel 120, i.e., the outer diameter of the sleeve 40 is larger than or equal to the inner diameter of the accommodating channel 120. The outer diameter of at least a part of the housing of the atomizing core 20 corresponds to at least a part of an inner diameter of the sleeve 40, such that the atomizing core 20 can be fixed in the accommodating channel 120 through the sleeve 40, so as to prevent the atomizing core 20 from shaking in the accommodating channel 120.

In one of the embodiments, as shown in FIG. 4, when the housing of the atomizing core 20 is a non-straight housing, the inner sidewall of the sleeve 40 may also be a non-straight sidewall, so as to fix the atomizing core 20 in the accommodating channel 120. When the sleeve 40 is sleeved on the housing of the atomizing core 20, it is only necessary that the inner diameter of part of the inner sidewall of the sleeve 40 corresponds to the outer diameter of a part of the housing of the atomizing core 20, such that at least a part of the inner sidewall of the sleeve 40 is in firm contact with at least a part of the housing of the atomizing core 20, thereby fixing the atomizing core 20 in the accommodating channel 120.

In order to adapt to atomizing cores 20 with different sizes, in one of the embodiments, two or more sleeves 40 are provided, which have different inner diameters. According to the size requirements, one of the sleeves 40 is selected to be disposed in the accommodating channel 120, and two or more sleeves 40 can be used alternately. In order to facilitate users to choose atomizing cores 20 with different sizes, and avoid purchasing a lot of atomizers to adapt to the size of the atomizing cores 20, and reduce the use cost for users, the plurality of sleeves 40 are provided to adapt to the atomizing cores 20 with different outer diameters, thus different atomizing cores can be fixed in the accommodating channel 120. In one of the embodiments, an inner diameter of the two or more sleeves 40 can be 8 mm, 9 mm, 10 mm, 11 mm, or 12 mm. The outer diameter of atomizing cores 20 commonly available in the market can be adapted by providing sleeves 40 with a plurality of sizes. In one of the embodiments, when an inner sidewall of the sleeve 40 is a non-straight surface, a minimum inner diameter of an inner sidewall of the sleeves 40 can be 8 mm, 9 mm, 10 mm, 11 mm, or 12 mm. The atomizing core 20 is a consumable and therefore needs to be replaced frequently, by providing the sleeves 40 with different sizes, the range of atomizing cores 20 purchased by the user can be expanded and the convenience of use can be improved.

As shown in FIG. 4, in one of the embodiments, when the number of sleeves is two or more, the outer diameters of each sleeve are the same, and the inner diameters of each sleeve are different, thus it can adapt to the atomizing cores 20 with different sizes. The outer diameters of each sleeve 40 are the same, such that each sleeve 40 is adapted to the size of the accommodating channel 120. Two or more sleeves 40 with commonly used size are provided for replacement.

In order to facilitate the sleeve 40 to be in communication with the liquid outlet 131, and enable the liquid to enter the atomizing core 20 through the sleeve 40, as shown in FIG. 3, in one of the embodiments, the sleeve 40 is provided with a first through hole 410, which is in communication with the liquid outlets 131. The liquid can flow through the first through hole 410 and the liquid outlet 131, and then enter the atomizing core 20. In one of the embodiments, two or more first through holes 410 can be provided. By increasing the number of the first through holes 410, the number of flowing-through channels of liquid is increased, and the liquid flow efficiency is improved. In one of the embodiments, the first through holes 410 correspond to the liquid outlets 131 in number and positions, respectively, so as to keep the liquid flowing smoothly.

In order to reduce the overall size of the atomizer, the size of the atomizer is similar to an external size of a real cigarette, and the user's use experience is improved. As shown in FIG. 3 to FIG. 5, in one of the embodiments, the sidewall of the sleeve 40 forms a part of the cavity wall of the liquid storage cavity 110. In order to optimize the distribution of the inner space of the atomizer, the partition wall 130 is designed to have a short size. When the partition wall 130 is too short, the partition wall 130 cannot form a complete cavity wall, which greatly exposes the liquid storage cavity 110 and the liquid storage cavity 110 cannot store the liquid. In this embodiment, the sidewall of the sleeve 40 is spliced with the partition wall 130 to form the cavity wall of the liquid storage cavity 110, and the sidewall of the sleeve 40 is used to complement the partition wall 130, thus forming a continuous and complete cavity wall of the liquid storage cavity 110, such that the occupied space of the liquid reservoir 10 is reduced while the liquid storage cavity 110 can store the liquid. The sidewall of the sleeve 40 can serve as the cavity wall and can fix the atomizing core 20. As shown in FIG. 4 and FIG. 7, in one of the embodiments, in order to facilitate the pushing of the mouthpiece 30, the inner diameter of the sleeve 40 is no less than the outer diameter of the mouthpiece 30, such that the mouthpiece 30 can smoothly enter the sleeve 40 and abut against the atomizing core 20, and it is convenient to push the mouthpiece 30 out of the accommodating channel 120 along the inner side of the sleeve 40. At the same time, the sidewall of the mouthpiece 30 blocks the first through hole 410 of the sleeve 40 to prevent liquid from leaking out of the first through hole 410. In this embodiment, the sidewall of the sleeve 40 is used as a part of the cavity wall of the liquid storage cavity 110. In order to save the occupied space, the partition wall 130 is provided with no liquid outlet 131, and the position occupied by the sidewall of the sleeve 40 is regarded as the position of the liquid outlet 131. In other embodiments, the liquid outlet 131 of the partition wall 130 is disposed at a position where it overlaps with the sleeve 40, and the first through hole 410 is also disposed at a position where it overlaps with the partition wall 130, such that the first through hole 410 is in communication with the liquid outlet 131 for easy circulation of liquid.

In order that the sidewall of the sleeve 40 is spliced with the partition wall 130 to form a continuous cavity wall, as shown in FIG. 3, in one of the embodiments, the sidewall of the sleeve 40 is configured to separate the liquid storage cavity 110 and the accommodating channel 120. The sidewall of the sleeve 40 and the partition wall 130 are at least partially overlapped, and the sidewall of the sleeve 40 is spliced with the partition wall 130 to form the cavity wall of the liquid storage cavity 110. Compared with the splicing method in which the end of the sidewall of the sleeve 40 directly abuts against the end of the partition wall 130, liquid can be prevented from leaking from the gap of the two after splicing through splicing by overlapping disposing. In one of the embodiments, in order to reduce the occupied space of the too thick overlapping portion of the sidewall of the sleeve 40 and the partition wall 130, the wall thickness of the overlapping portion of the sidewall of the sleeve 40 and the partition wall 130 is reduced. That is, the wall thickness of the sidewall of the sleeve 40 of the overlapping portion and the wall thickness of the partition wall 130 of the overlapping portion are reduced, such that the thickness of the two after overlapping is no greater than the initial thickness of the sidewall of the sleeve 40 or the partition wall 130, the occupied space of the overlapping portion is reduced, and the volume of the liquid storage cavity 110 is kept maximum.

In order to limit the overlapping depth of the sidewall of the sleeve 40 and the partition wall 130, as shown in FIG. 3 and FIG. 4, in one of the embodiments, the sidewall of the sleeve 40 or/and the partition wall 130 is provided with a limit protrusion 420. In other words, both the sidewall of the sleeve 40 and the partition wall 130 are provided with limit protrusions 420, or only one of them is provided with the limit protrusion 420. When the sidewall of the sleeve 40 is provided with the limit protrusion 420, the limit protrusion 420 is disposed at a side thereof adjacent to the accommodating channel 120, such that an end of the partition wall 130 abuts against the limit protrusion 420. When the sidewall of the sleeve 40 and the partition wall 130 are overlapped, the mutual position of the sidewall of the sleeve 40 and the partition wall 130 can be quickly determined by the abutting of the limit protrusion, thereby keeping the position of the two fixed. Similarly, when the partition wall 130 is provided with the limit protrusion 420, the limit protrusion 420 is disposed at a side thereof adjacent to the liquid storage cavity 110, such that the end of the sidewall of the sleeve 40 abuts against the limit protrusion 420. The position of the sidewall of the sleeve 40 and the partition wall 130 is defined by the limit protrusion 420, and the rapid disassembly and assembly of the sleeve 40 and the liquid reservoir 10 can also be achieved.

In order to prevent liquid in the liquid storage cavity 110 from leaking out from the gap of the overlapping portion, as shown in FIG. 3 and FIG. 4, in one of the embodiments, the sleeve 40 is provided with a first anti-leak groove 430 on a sidewall thereof overlapping the partition wall 130. By providing the first anti-leak groove 430 on the overlapping portion, when liquid leaks into the gap of the overlapping portion, liquid can be buffered and stored in the first anti-leak groove 430 to prevent liquid from leaking out from the gap of the overlapping portion.

If liquid leaks out from the gap of the overlapping portion, it will then flow into the accommodating channel 120 instead of the atomizing core 20, thus eventually contaminating the accommodating channel 120 and even flow out of the accommodating channel 120 to the outside of the atomizer, which will contaminate the atomizer 20 and at the same time, waste liquid. In order to further prevent liquid from leaking out of the gap of the overlapping portion into the accommodating channel 120 and flowing out of the accommodating channel 120 to the outside of the atomizer, as shown in FIG. 3 and FIG. 4, in one of the embodiments, the mouthpiece 30 is provided with a second anti-leak groove 320 on the outer sidewall thereof.

Users can choose different sleeves 40 to replace according to the model of the atomizing core 20 actually used. The step of replacing the sleeve 40 is as follows: firstly, the atomizing core 20 is pulled out of the accommodating channel 120, and then the fixing base 50 is removed from the liquid reservoir 10. Then, the flange 610 of the sealing seat 60 is grasped, and the sealing seat 60 is taken out of the liquid storage cavity 110, and then the sleeve 40 can be taken out. Finally, a new sleeve 40 with a different size is assembled according to the above assembly sequence.

When the atomizer needs to be cleaned, the detachment steps of the atomizer in this embodiment are as follows.

Firstly, the mouthpiece 30 and the atomizing core 20 are pulled out from both ends of the accommodating channel 120, respectively. Then, the fixing base 50 is removed, and then the flange 610 of the sealing seat 50 is grasped, and the sealing seat 50 is taken out of the liquid storage cavity 110, and then the sleeve 40 is taken out, and finally the reservoir cover 160 is pulled out of the liquid reservoir 10. In this way, the disassembly of the atomizer is completed, which is quick and convenient. Users can clean each component separately to keep the atomizer clean and hygienic. The first seal ring 210, the second seal ring 620, and the third seal ring 240 can be respectively removed and cleaned, such that the first positioning groove 220, the second limit groove 630, and the third limit groove 250 can be cleaned thoroughly. Because the atomizing core 20 has electrical parts, the atomizing core 20 is not suitable for washing. After using the atomizing core 20 for a period of time, it can be replaced by a new one directly, which is more hygienic.

The structure of the atomizer of the present disclosure is convenient for users to disassemble and assemble with bare hands, without tools, and is quick and convenient.
